ATTACI-IING TOOLS TO HANDLES.

Specification of Letters Patent No. 19,606, dated March 9, 1858.

T0 all whom t may concern w Be it known that I, JOHN HENN, of New lBritain, in the county o-f Hartford and State made square to fit intothe handle H. This square part is cut away at the back side, so as toform a recess, a, with the knife or tool part, and which fits againstthe spring S, in the handle, and upon t-he top of said handle therebygiving the knife or tool a firm bearing when fixed in the handle.

n, is a. slit, running diagonally from the front side of the squarepart, downward, and finishing toward the middle of said square part in acircular opening corresponding with a pin, 79, securely fastened in thehandle H. In the back part of the handle H a spring S, is fitted capableof turning near its middle upon a pin, m. The upper end of this spring Sis provided with a small nose, d, and corresponds otherwise exactly withthe recess, a. On the lower end of the handle, H, a plate, fw, isattached, 'on the inner side of which a projection or cam D is fixed,turning eccentrically upon a pin, g, so as to press against the spring,S, and hold the same fast, when the plate, fw, is closed, and to relievesaid spring, and allow the same to turn on the pin, m, for the purposeof taking out or putting in a knife or tool into the handle H.

When the plate, fw, is opened, as represented in Fig. II, and thespring, S, turned back, any one of the knives 0r tools can be attachedto the handle by hanging the same on the pin, p, passed through theslit, n., after which the plate, fw, will be closed whereby theprojection D acts against the lower end of the spring, S, forcing theupper end inward and thereby locking the knife or tool firmly in itsplace.

What I claim as my invention and desire to secure by Letters. Patent is:

The arrangement and construction ofthe plate, fw, with projection, D,acting against a spring in the back o-f a handle in such a manner, thatwhen opened it will relieve said vspring to allow a knife or tool to beattached to the upper end of said handle, and" when closed, force thespring against the tool so as to hold the same perfectly steady in thehandle substantially as described.
